Steven Spielberg had to stop watching the film halfway through on a home screener as he was genuinely spooked by the experience. He completed it in daylight hours the next day and loved it.

Jaws

"You're gonna need a bigger boat" was not scripted but ad-libbed by Roy Scheider.

The shooting star that appears during the night scene where Brody loads his revolver was real, not an optical effect.

Rocky

Rocky is not the character's actual name. His real name is Robert Balboa - this was seen in a rough script from the second film.

While You Were Sleeping

Harrison Ford and Geena Davis were initially offered this film.

Lord of the Rings: Fellowship of the Ring

John Rhys-Davies, who plays Gimli the dwarf, is the tallest of the actors who play members of the Fellowship. He is 6' 1".

Pretty Woman

Edward (Richard Gere) snapping the necklace case down on Vivian's (Julia Roberts) fingers, was improvised by Gere, and Roberts's reaction (laughter) was totally natural. The filmmakers liked it so much, they decided to leave it in.

Titanic

The hands seen sketching Rose are not Leonardo DiCaprio's, but director James Cameron's.

Alien

Ridley Scott stated that in casting the role of Ripley, it ultimately came down to Sigourney Weaver and Meryl Streep.

The slime used on the Alien was K-Y jelly.

Exorcist

The refrigerated bedroom set was cooled with four air conditioners and temperatures would plunge below 30 degrees.

Godfather

Marlon Brando did not memorize most of his lines and read from cue cards during most of the film.

Whenever oranges appear in the film, they foreshadow death or a near death.

American Werewolf in London

It was filmed in sequence, with the opening scenes filmed first and the closing sequences filmed last.

The Blues Brothers

The Bluesmobile was actually going 118 miles per hour under the elevated train line. Stunt pedestrians were added after the first pass to add realism.

Silence of the Lambs

The first moth cocoon found in one of the victim's throats was made from a combination of Tootsie Rolls and gummy bears, so it would be edible if swallowed.

Field of Dreams

The shot of the line-drive knocking over the bag of baseballs next to Kevin Costner was sheer luck off the bat of Ray Liotta.

"The Final Shot" was a big community event, enlisting 1,500 volunteers to drive for the last scene.

The Thing

John Carpenter and Kurt Russell both admit that after all of these years they still do not know who has been replaced by the creature and when.

Exteriors were shot in Stewart, British Columbia. The temperature ranged between 0 F and -15 F during the shoot.

Terminator

Near the beginning of the movie the voice on Sarah Connor's answering machine is James Cameron's.

O.J. Simpson was considered for the Terminator, but the producers feared he was "too nice" to be taken seriously as a cold-blooded killer.

Predator

The original concept for this film originated as a joke. Someone said that the only person Rocky Balboa of the Rocky series of films had yet to fight was E.T. the Extra-Terrestrial.

Lethal Weapon

The first movie to feature a cellphone.

Die Hard

The Nakatomi tower is actually the headquarters of 20th Century Fox.

Clint Eastwood originally owned the rights to the novel "Nothing Lasts Forever" on which the film is based, and planned to star in the film around the early 1980s.

Raiders of the Lost Ark

Harrison Ford actually outran the boulder in the opening sequence. Because the scene was shot twice from five different angles, he had to outrun it ten times. Ford's stumble in the scene was deemed to look authentic and was left in.

Jeff Bridges turned down the role of Indiana Jones.

The Well of Souls sequence was filmed on the set of the Overlook Hotel from The Shining

Ghost

The horrific sounds made by the "dark shadows" are really the sounds of baby's cries, played at extremely slow speed backwards.

Smokey and the Bandit

Was a Guilty Pleasure of Alfred Hitchcock

The second highest grossing movie released in 1977 next to Star Wars: Episode IV - A New Hope

Breakfast Club

John Hughes wrote the screenplay to this movie in just two days (4 and 5 July 1982).

Shawshank Redemption

The film's initial gross of $18 million didn't even cover the cost of its production. It did another $10 million in the wake of its Oscar nominations but the film was still deemed to be a box office flop.

The water Tim Robbins crawled though to freedom was a mix of sawdust, chocolate syrup and water.

Bruce Willis was originally cast as Danny Ocean, but had to pull out due to scheduling conflicts.

The name of Carl Reiner's character Lymon Zerga sounds like the Spanish phrase "la monserga" which translated into English roughly means, someone who is a pain in the butt.

Batman Begins

When Christian Bale and Liam Neeson were fighting on the frozen lake they could hear the ice cracking beneath their feet. The next day, the lake was completely melted.

Ra's Al Ghul is Arabic for "The Demon's Head".

Pirates of the Carribean: The Curse of the Black Pearl

The final cannon shot during the Black Pearl's siege of the town, billows into a Mickey Mouse head shape against the night sky.

Having decided that pirates were the 18th century equivalent of rock stars, Johnny Depp's characterization of Sparrow was inspired by close observation of his friend Keith Richards, though he emphasized in interviews that it was not an impersonation.

Dirty Harry

Clint Eastwood performed all his own stunts, including the stunt where he jumps onto the roof of the hijacked school bus from a bridge. His face is clearly visible throughout the shot.

When Harry walks into the hot dog joint before the robbery shootout scene, there's a movie marquee to the right of the screen as Harry walks into the restaurant. The movie that's showing is 'Play Misty for Me' - a movie starring and directed by ... Clint Eastwood.

The Lord of the Rings: The Two Towers

Viggo Mortensen broke two toes while kicking the steel helmet by the orc pyre, and that take is the one that actually appears in the movie. Peter Jackson said that he was really impressed with the shout of pain Aragorn cried out for the fate of the two hobbits.

The Lembas Bread that Sam and Frodo eat was actually shortbread cookies.

There were never more than 100 Uruk-hai at any time; the rest were all computer generated.

First Blood

Al Pacino was considered for the role of John Rambo, but turned it down when his request that Rambo be more of a madman was rejected.

Star Trek (2009)

When Chekov manages to transport Sulu and Kirk aboard from a fall, he shouts "Yo-moyo!" This is a Russian exclamation of surprise and excitement, roughly corresponding to English "Hot damn!"

To perfect the Vulcan salute, Zachary Quinto had his fingers glued together.

The Quiet Man

Production was a real family affair:

Barry Fitzgerald, who plays the character of the Roman Catholic Michaleen Oge Flynn, and Arthur Shields, who played the Protestant vicar Cyril 'Snuffy' Playfair, were brothers in real life.

The white haired frail Dan Tobin, who gets up from his death bed and runs to see the fight is John Ford's older brother, Francis Ford.

Jamie Lee Curtis buried her face in pillows during Kevin Kline's ejaculation scene, to keep her from bursting out laughing at the faces he was making.

The fish that Kevin Kline eats are made out of Jello. Kline claims that he offered to eat real, live fish, but the filmmakers wouldn't let him.

Fast Times at Ridgemont High

For his masturbation scene, Judge Reinhold brought a large dildo to work with, unbeknown to the rest of the cast. Phoebe Cates' look of horror and disgust is very real.

Justine Bateman was offered the role of Linda but declined. Instead, she preferred to star in the TV series Family Ties which ran for 7 years.

Twins

Schwarzenegger got 20% of the profits, and made $35,000,000 through international sales, video/DVD sales and TV screenings. He earned more money from Twins (1988) than any of the Terminator movies.

Risky Business

Sean Penn makes a cameo as the man sitting in the passenger seat as Joel first takes the Porsche for a spin.

Ferris Bueller's Day Off

To produce the desired drugged-out effect for his role as the drug addict in the police station, Charlie Sheen stayed awake for more than 48 hours before the scene was shot.

Mia Sara says that Matthew Broderick actually tickled her feet and knees to get her to laugh naturally in the taxicab scene.

Home Alone

In the original script, Uncle Frank was the real mastermind behind Harry and Marv robbing the McAllister house.

There is a legend that Elvis Presley (who died in 1977) makes a cameo in this movie. Many of those who believe that Elvis is still alive maintain that the heavily bearded man standing in the background of the scene where Mrs. McCallister is shouting at the desk clerk (just before she meets John Candy) is Elvis.
